How does a barometer predict weather?
The basic rules of thumb are: If the barometer measures low air pressure, the weather is bad; if high pressure, it is good. If pressure is falling, then the weather will get worse; if rising, better. The faster it is falling or rising, the faster and more the weather will change.
